Replacing Instant Hot Water Systems

While modern instant hot water systems are durable, they eventually retire and require replacement.

Replacing a tankless system needs both plumber and gas fitter experts to make sure the installation meets every compliance rule.

Our professional fitting quickly and cleanly modernises your system, meaning the new unit delivers full efficiency for another twenty years!

Types of Instant Hot Water Systems

The main decision you face when moving to continuous flow is choosing between a gas or an electric power source.

Both of these systems remove the large storage tank but use totally different technology to heat your water instantly.

We manage the precise installation of both systems across Melbourne.

Gas Instant Hot Water Systems

Gas systems are the most common instantaneous systems in Melbourne and are valued for their powerful heating ability.

🔥 Technology: Gas systems heat water instantly using a powerful heat exchanger. This gives you a high flow rate, which is why they work best for busy homes with multiple bathrooms..

🔥 Installation: Because these systems are compact, they only require exterior wall mounting. This quickly frees up valuable interior and outdoor space where your old tank used to sit.

Electric Instant Hot Water Systems

Electric instantaneous systems are compact and easy to install. They require no gas line or exterior venting.

⚡ Technology: They use electrical elements to heat the water. Their lower flow rate means they are mainly suited for apartments, small homes, or dedicated single taps.

⚡ Installation: Due to the unit's small size, installation is flexible. We can place it closer to the point of use (like under a sink) to minimise lag and water waste.

Instant Hot Water System Repairs

Unlike storage tanks, modern instant water heaters use complex electronics and sensors. This calls for a plumber with specialised skill to find the fault.

When your instant hot water unit fails, you need an experienced plumber who knows this modern technology inside out.

Our expert plumbers quicklyfind and fix the difficult problems, such as ignition faults, gas solenoid failure, and temperature issues.

We use only genuine manufacturer parts for your repairs. This brings back your unit's precise performance and makes sure it lasts a long time.

Instant Hot Water Servicing

Routine maintenance for your instant system is not optional: it’s essential to prevent common efficiency killers like scale build up and electronic drift. 

Because these tankless hot water systems are so precise, they need specialised attention to maintain performance.

Our licensed plumbers focus on deep cleaning the heat exchanger to remove scale. This makes sure you get the best flow and that the unit lasts longer.

We check the gas valves and sensors to make sure the unit delivers instant hot water and the correct temperature every time.

Instant Hot Water System Installation

installing an instant hot water system is a specialised task that requires careful plumbing and gas fitting. 

Our GRH plumbers manage the whole job, making sure the process is quick and tidy.

We manage the removal and disposal of your old, bulky storage tank, then carefully fit the compact instantaneous unit to an exterior wall.

We guarantee this installation is safe and compliant. It delivers the best efficiency and frees up that valuable outdoor space right away!
